Question

Calculate the percentage yield of the alcohol and submit the ethanol to the instructor in a labeled vial.3 1. Write a balanced equation for the conversion of sucrose into ethanol. 2. By doing some library research, see whether you can find the commercial method or methods used to produce absolute ethanol 3. Why is the air trap necessary in the fermentation? 4. How does acetaldehyde impurity arise in the fermentation? 5. The diethylacetal of acetaldehyde can be detected by gas chromatography. How does this impurity arise in fermentation? 6. Calculate how many milliliters of carbon dioxide would be theoretically produced from 20 g of sucrose at 25°C and 1 atmosphere pressure.
Can you please answering those questions from 1 to 6?

Answer 1

1. Sucrose can be converted into ethanol through biochemical process of fermentation.

The reaction proceeds as :

GH₂2O + H2O → 4 CH 04 + 4CO₂ (Ethanol) (Sucrose)
